This role sets technical direction on the hardest connected-architecture problems in the portfolio and holds the technical standard that internal developers and external partners build against. The Principal Engineer designs the connected-platform interfaces and standards, then writes the reference implementations - connectivity stacks, provisioning and pairing code, display/UI frameworks, and app/cloud integration layers - that prove the architecture out in working code before any partner builds against it. That combination is what gives this role its leverage: not just interface contracts and design reviews, but hands-on implementation that sets the technical bar for the hardest connected-architecture problems in the portfolio. This is an architect-track role for an engineer who wants deep technical scope in connected systems without moving into people management., Technical Direction * Define reference architectures and reference implementations for wireless connectivity, display/UI, and app/cloud integration reused across product categories. * Own the design of the most technically demanding connected subsystems - Bluetooth/BLE and Wi-Fi stacks, Matter/Thread/Zigbee integration, display and embedded UI frameworks, and device provisioning and pairing protocols. * Make and document the technical decisions that constrain downstream implementation: connectivity interface contracts, app/cloud API boundaries, and wireless platform selection criteria. * Prototype and de-risk new connectivity, display, and app-integration technologies ahead of program commitment. Design Review & Partner Governance * Lead technical design reviews for internal and partner-developed connected firmware; approve or reject against defined criteria. * Translate architectural intent into requirements that partners can execute without interpretation. * Serve as the technical escalation point for partner design disputes and interoperability or integration failures. * Assess partner technical capability in wireless and display subsystems and contribute to consolidation and qualification decisions. Certification & Standards Engineering * Provide the technical depth behind certification submissions - Bluetooth SIG, Wi-Fi Alliance, Matter - and own root-cause resolution when a submission fails. * Track relevant wireless standards evolution and inform architecture decisions ahead of spec changes. * Define the reproducibility standard in technical terms for connected subsystems - source, toolchain, and build manifest requirements sufficient for independent rebuild of shipping binaries. Engineering Standards & Infrastructure * Contribute to the test automation framework for connectivity and display subsystems: CI pipeline design, RF and interoperability test-harness infrastructure, static analysis configuration. * Establish and evolve coding standards, review criteria, and quality thresholds applied across internal and supplier connected-firmware codebases. Technical Leadership & Mentorship * Provide technical direction to the connected-track Senior Embedded Firmware Developer; mentor senior and mid-level engineers across US and China teams working on connected features. * Partner with Hardware Engineering, Systems, Cloud, Mobile App, and NPD to gate critical connected-product behavior at design time. * Represent connected firmware technical positions in cross-functional and executive forums.
